Quotes turn a number into text.
Python sorts every value into a . Text in quotes is a string. A whole number with no quotes, like 12, is an . Same digits, different type, and Python treats them very differently.
Picture a front door with 12 painted on it, and a box of 12 eggs. The door number is a label you read, like "12". The eggs are an amount you can count and add, like 12.
Not sure which one you have? Ask type(). Its answer includes str for a string or int for an integer.
print(type("12"))
print(type(12))
print(12 + 12)A number inside quotes is text, even when it looks like a number.
guess first
What will the scoreboard show?
Guess before you run it. Wrong guesses are how you learn, and nothing is marked.
home_goals = "2"
away_goals = "1"
print(home_goals + away_goals)your turn

bakedis an integer. - Remove the quotes so line 1 reads
cookies = 4, then press run.

type()tells you what kind of value you have.
